Is my Meter Clock E7 or E10 - see photos

Michael_Stobswell

Hi,
Just moved to a new house. Not sure what time the night tariff starts according to the clock. Please someone who knows help.

The picture is taken at 14:15. What time is my night tariff and is there more than one tariff?

Also my storage heaters are off and cold. Is it possible to be a switch connected to the clock so they turn on only at night tariff?
Please see the photo below, is this a potential automatic e7 switch?

Thank you in advance.

looks like E10 . The timer switch pointer thinks its 12.45 pm , so if you took the photo at 14.15 pm then its an hour and a half out at the moment.when the clocks go forward that will change.
I never see e10 or white meter timerswitches. E7 just has three pointers.. On, /Off for the 7 hrs and one for the present time which on that photo appears to be at 12 .45 ish.
Best thing is to try and observe the day/night /boost meters when any one starts to advance. Only the occupier can work this one out.

The second picture is a separate 40A circuit. Cooker, shower, garage ?

Storage heaters should be wired to either their own consumer unit or one half of a split load box wired in only to the off peak output of the timer.

Some odd switching times on that timer. Is it actually sealed so you cannot adjust it yourself ? You are getting 11.75 hours off peak. E10 in Scotland should have something like 0430-0730, 1330-1630 & 2030-0030. The time is also out, it is reading 12.45. Your clock timings are 1600-1700, 2230-0715 & 0900-1100 but is actually live at 1730-1830, 00.00-0845 & 1030-1230. All times GMT. After the end of he month they come on an extra hour later.

The timer clocks are protected with an official seal. Can t have people adjusting it to suit how long they want the cheap rate to stay on molerat.. That is energy theft

I know that which is why I asked if it was actually sealed and I was not suggesting that op do that but that it has already been done as the times set are very strange.

Yes they are all over the place. OP check that there is a small wire seal on one corner of the time switch.Someones maybe been in it for a fiddle around.
Suppliers do come out to adjust an incorrect time clock and Scottish Power are the only supplier who actually care about the correct timings on time switch clocks. If more than 2 hrs adrift they ask us to note it. The others, incl BG, Eon, EDF are not interested
These complex meter set ups usually have Radio Teleswitch controlled timers.Very accurate and do not drift out of time

That looks like the sort of timeswitch that used to be in my father's house until about 20 years ago. It gives an afternoon boost which is required by old fashioned foot thick storage heaters.

Hi all,

Thanks for the help. The clock is sealed at the bottom, plus I know not to touch anything anyway. I called Scottish Power and they said they put the meters there themselves in 1996. So, I presume since that time the clock has been like that.

Interesting you say that about the radio teleswitch. I always wondered how accurate those things really are, and then I saw this recently

From what I can see, the unit switches the dedicated E7 circuits on 1 hour before it switches to counting on the night rate.

Granted it could have been fiddled with, but it is worth checking those teleswitches once in a while and ensuring the use is being counted on the correct rate.

Reliable piece of kit though.

Interesting Youtube vid CashStrapped.

Radio Teleswitch stick to GMT all year so its an hour out in BST.
All digital timers seem to stay in GMT but I m sure smart meters can be programmed to switch to BST. I have nt seen any Eco 7 smart meters in use so far for some strange reason at least not with BG, EDF, Scot Power as of yet.
Interesting Youtube vid CashStrapped. It was a Scottish switch so maybe its set up for their "white meter " timings which have boost as well as the normal 7 hrs. I have checked them occasionally and watched them switch over from night to day, they are always more or less on time to a minute or so unlike the digital Ampy meters where I ve seen their timers drift as much as 4 hrs. I n a meter room with over 60 eco 7 digital meters I hear them clicking over from night to day throughout the morning with hardly any of them around the 8.30 am (BST ) official times.
Smart Eco 7 should end all this , their clocks will stay on time.. I d guess !
Would be good to know that when you have say, a shower that you re not paying double the kwh rate due to a faulty time switch

I'm guessing the radio teleswitched have a bit of random delay built in otherwise the network would come to a grinding halt if all of them switched at exactly the same time.

A whole estate (or even street) of houses each suddenly bunging on 25kw all at the same time could prove interesting.
